This rare vintage Native American handmade Sterling silver concho belt was created by a Navajo (Diné) master craftsman for Southwest Arts & Crafts, Santa Fe, New Mexico circa 1946. This is indicated by the "UITA 21" found on the reverse of the buckle. The United Indian Traders Association, or UITA, was founded in 1931 with express purpose of authentication of Indian crafts. This group of Forty leading Native American Arts dealers began applying the "UITA" mark to Native American jewelry in 1946 after the IACB, or the Indian Arts and Crafts Board of the US Department of the Interior, ended its program of applying marks to authentic, high quality, Native American made silver jewelry in 1943. Belts of this quality are extremely hard to find. Add to that the historical significance of this masterpiece and its importance cannot be denied. Check out the deep and precise hand stamping on the buckle. Four distinct stamps were combined to create the beautiful floral designs at each end of the belt. The smith who created this exquisite belt them combined four stamps with deep repousse to create another traditional, yet, unique design. Four more stamps were used to chase the intricately scalloped edge of the buckle. Straight lines were then incised to draw all of the elements together. No less beautiful, yet seemingly simple, are the individual conchas. They are scalloped and chased on the edges with an oval repousse in the middle of each shell. Incised lines then draw the eye to an unusually deep diamond repousse at the center of each. WOW! The person who executed these conchas was a true master. Copper straps attach each concha to the still supple black leather belt. The tongue on the buckle is also made of Sterling. No collection of Native American jewelry is complete without a piece with a UITA mark. DO NOT MISS OUT ON YOUR CHANCE TO OWN A PIECE OF HISTORY!
